BRAIDINGi-IVIACHINE RACER.

SPECIFICATION forming part of Letters Patent No. 575,428, dated January19, 1897.

Application I'led October 29, 1896. Serial No. 610,492. (No model.)

To @ZZ whom t may concern.-

Be it known that I, ORLAND E. MOORE, a citizen of the United States ofAmerica, resid ing at Vestiield, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements in Braiding-Machine Racers, of which the following is a speciiication.

This invention relates to braiding-machines, and particularly to racersfor use in such machines, the object being to provide a racer ofimproved construction and particularly in re lation to the tensiondevices thereon which act upon the strips of material which are drawnfrom the racer in the formation of a braided whip-lash or other braidedfabric; and the invention consists in the peculiar construction andarrangement of various parts of the device, all as hereinafter fullydescribed, and more particularly pointed out in the claims.

In the drawings forming part of this specifica-tion, Figures l, 2, and 3are respectively front, rear, and edge elevations of a racer embodyingmy improvements. Fig. 4 illustrates detail parts of the devicehereinafter described.

Referring to the drawings, A indicates the frame or body of the racer,which is preferably cast in one piece, and the integral parts thereofcomprise the upperand lower fixed jaws, respectively, (indicated by 2and 5,) the fixed support 3 for one of the tension-rollers, the foot aof the racer, and the tension-screw boss or stud 6. To'said frame orbodyare attached the below-described operative parts of the racer. Asuitable stud or spindle (indicated in dotted lines in Fig. 3) is fixedto the front side of said body A, projecting therefrom at right angles,on which a spool or bobbin B is hung for substantially free rotarymovement, induced by drawing a strip of material therefrom, as below setforth. Said bobbin is provided with a projecting stud 7 on its frontend, to which may be applied any suitable device for turning the same towinda strip 8 of braiding material thereupon, or a central rectangularsocket may be made in said front end to receive the shank. of awinding-crank. A retarding-spring 9, Fig. 1, having one end fixed tosaid frame A, has its free end bearing frictionally against theperiphery of one head of said spool in order to maintain a certaindegree of tension upon said braiding material while it is being drawnfrom said bobbin, as below set forth., thereby preventing the materialfrom becom ing loose and displaced thereon. Avibratory tension-rollersupport D is pivotally hung on said frame or body A upon a suitable boltor screw 10, the upper extremity of which terminates opposite said fixedroller-supporting part 3 of frame A, and upon said fixed part and saidextremity of said support D are j ournaled two fluted or corrugatedtension-rollers 12 and 13 having suitable broken surfaces for grippingpurposes,which rotate upon suitable pivotal axes or the screws 14.Between the under sides of the heads of said screws 1a and the outerends of said tension-rollers are placed coil or other springs 15 forfrictional action against the ends of said rollers, whereby they arerestrained from rotation excepting by the action of a strip of saidbraiding material 8, while the latter is drawn between them, asaforesaid. A guide-hook 16 for said material 8 is fixed in the frame Ajust below said fixed jaw 5. The said tension-roller support has itslower extremity extending downward opposite said fixed stud 6 on theframe A and has a slot 17 therethrough, Fig. 3. A thumb-screw 18 has ascrew engagement with said stud l5 on the frame A and has a shoulder 19thereon, forming an abutment for one end of a coilspring 20 on saidscrew, the opposite end of which springbears against thelower end ofsaid roller-support D, a loose washer 21 being placed between one end ofsaid spring 2O and the adjoining side of said support to form a properabutting surface for that end of the spring. By means of saidthumb-screw 18 `and spring 2O the desired gripping pressure against thestrip of material 8 as it is drawn between the said two rollers 12 and13 in the operation of braiding is properly regulated. Aforwardly-projecting arm 22 is provided on said roller-support D,preferably integral therewith, to provide for the convenientImanipulation of said support in swinging the same to move the roller 13away from the opposite roller 12 and free the strip 8 from the grip ofsaid rollers. A jaw 23, similar to said opposite jaw 5, is provided onthe said support D, said two jaws serving to guide said braiding-strip8. A second jaw 24E is provided on said support D, so arranged that oneedge thereof shuts more or less under said jaw 2 on the frame A, (seeFigs. l and 4,) thereby imparting a certain degree of tension to saidstrip 8 in addition to that derived from said rollers 12 and 13.

The within described racer provides a strong construction particularlyadapted to machines for braiding whip-lashes, window and other similarcords of textile material, and contains tensioncontrolling devicesparticularly adapted to such manufacture, and is a simple andinexpensive machine. In using the within-described racer on a certain orregular grade of braided Work adjustable gripping devices, including`the screw 18 and spring 20, are not required. Therefore a spring, as 20,or other suitable constant-terr' sion spring engaging by one end a partof the frame, directly or indirectly, and by its opposite end the lowerend of the support D may be used, and in that case said screw may beomitted.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. A braiding-machine racer comprising a body, two jaws and atensionscrew-supporting stud on said body, combined with a roughfacedtension-roller j ournaled on said body between said jaws, atension-roller support pivotallyhung on said bodyhaving jaws thereon, arough-faced tension-roller j ournaled on said support opposite saidfirst-named roller, tension devices supported on said stud and engagingone end ot' said support, whereby the position of one of saidtension-rollers is made variable relative to the other, and a bobbin forbraiding material supported revolubly on said body` substantially as setforth.

2. A braiding-machine racer comprising a body, two jaws and atension-screw-supporting stud on said body, combined witha roughfacedtension-roller journaled on said body between said jaws, aroller-support pivotally hung on said body having jaws thereon, arough-faced tension-roller journaled on said support between the jawsthereon and opposite said first-named roller, a tension-spring and screwacting between said stud and engaging one end of said support, wherebyone of said tension-rollers is moved toward and from the other, and abobbin for braiding material supported revolubly on said body,substantially as set forth.

3. A braiding-machine racer comprising a body, two jaws and atension-screw-supporting stud, said jaws and stud being integral withsaid body, combined with a grooved tension-roller journaled on said bodybetween said jaws, a tension-roller support pivotally hung on said bodyhaving jaws thereon, and a slotted lower extremity, a groovedtensionroller journaled on said support between the said jaws thereon,and opposite said firstnamed roller, a tension-screw engaging said studand extending through said slotted lower extremity of saidroller-support, a spring on said screw compressible by the latteragainst said support, whereby the latter is vibrated and one of saidtension-rollers is adjusted toward and from the opposite roller, abobbin for braiding material supported revolubly on said body, and arestraining-spring for frictional contact with said bobbin,substantially as set forth.

4.
